The icosathlon, also called the double decathlon, is an ultra multi-event of track and field competition consisting of 20 events contested over two days. There is an extra rule, that each day should contain a pause of one hour. Mostly the competition is held over two days, but one-day icosathlons also exist. The first day of the standard icosathlon includes:
- 100 metres
- Long jump
- 200 metre hurdles
- Shot put
- 5000 metres
- pause
- 800 metres
- High jump
- 400 metres
- Hammer throw
- 3000 meter steeplechase
On the second day of the standard icosathlon, the following events are contested:
- 110 metre hurdles
- Discus throw
- 200 metres
- Pole vault
- 3000 metres
- pause
- 400 metre hurdles
- Javelin throw
- 1500 metres
- Triple jump
- 10000 m
Each event is scored according to the decathlon scoring tables or, for non-decathlon events, the IAAF points tables. At the conclusion of each icosathlon, the competitor with the highest point total is declared the winner.
The event is overseen by the International Association for Ultra Multievents (IAUM), which also holds the tetradecathlon based on the women's heptathlon. The men's world record for the standard icosathlon of 14,571 is held by Joseph Detmer of the United States. The women's world record of 11,091 is held by Kelly Rodmell.
